| Variations in the lithium abundances of turn off stars in the globular cluster 47 Tuc (2007) | |||||||||
Abstract | |||||||||
| aims: Our aim is to determine Li abundances in TO stars of the Globular Cluster 47 Tuc and test theories about Li variations among TO stars. method: We make use of high resolution (R~ 43000), high signal-to-noise ratio (S/N=50--70) spectra of 4 turn off (TO) stars obtained with the UVES spectrograph at the 8.2m VLT Kueyen telescope. results: The four stars observed, span the range 1.6. Comment: recommended for publication in A&A by the managing associate Editor | |||||||||
